In the "Opinel" thread in Knife Reviews & Testing, there's a claim about "multiple reports of problems" with the Axis lock. I only ever read one complaint about an axis lock filling with dirt and one complaint about a broken spring. My 710 and 705 have served me well for years with nary a problem. I know several people with Axis lock knives, and they all love the system. Am I totally clueless here? Are Axis locks really POS's in disguise and I'm the last guy to know about it, or are they simply one of the best locking mechanisms available like I've always thought?
